# Device drivers

## Overview

The current device drivers are scattered through the `shelter/lib/include/devs` folder. There is two kinds of devices drivers:
- integrated: these one are used as a core part of the kernel, and aren't exposed through subsystem abstraction
- abstracted: these one are abstracted using a specific subsystem depending on the device type that provides a standard API both for drivers and consumers

## Integrated drivers

For the moment, integrated drivers are implemented for the following devices:
- [LAPIC devices](integrated/lapic.md)
- [IOAPIC devices](integrated/ioapic.md)

## Abstracted drivers

For the moment, abstracted drivers are implemented for the following devices:
- [PS2 keyboard](abstracted/ps2.md)
